Query returns no rows in pg_basebackup cluster

Hi!

In windows pg_basebackup was used to create base backup from Linux server.
baas column data type is character(8)

In Linux server query

select * from firma1.desktop where baas='_LOGIFAI'

returns 16 rows.

Windows server this query returns 0 rows.

In Windows server same query using like

select * from firma1.desktop where baas like '_LOGIFAI'

returns properly 16 rows.

Maybe this is because database locale is not known in windows:

CREATE DATABASE sba
WITH
OWNER = sba_owner
ENCODING = 'UTF8'
LC_COLLATE = 'et_EE.UTF-8'
LC_CTYPE = 'et_EE.UTF-8'
TABLESPACE = pg_default
CONNECTION LIMIT = -1;

Correct encoding for windows should be

LC_COLLATE = 'Estonian_Estonia.1257'
LC_CTYPE = 'Estonian_Estonia.1257'

IF so how to to fix windows cluster so that query returns proper result in windows also?
Database in Windows is in read-only (recovery) mode so it cannot changed.
Postgres 12 is used.
